Claying you would get away with mate as it removes mostly the dirt thats engrained into the paintwork, so takes off minimal lacquer. I'm peed off with DD's Bonnet and VTiS lip, both are stone chipped to hell (bumper is fine though as it was brand new from Honda). The bonnet looks awful close up as its litterally thousands of tiny wee white dots. Can't wait to get the garage built and kitted out. Think one of the first jobs will be respraying the bonnet and lip on DD! Rest of her paintwork is ok, comes up nice with a clay/polish/wax. I'd go for it mate, nothing nicer than super polished Pirates Black paint in the sun!!
